Benefits of technology
This integration improves cooling efficiency, reduces the number of connection members, and increases the number of battery cells per module, enhancing assembly performance and energy density while ensuring safer operation by minimizing heat conduction distance and promoting uniform cooling across the battery pack.
Problems solved by technology
At this time, if the heat of the battery module is not effectively removed therefrom, a deterioration of the battery module may be accelerated, or safety problems such as ignition or explosion may occur.
In this case, there is a problem that a degree of cooling varies depending on the location of each of the battery modules.
For example, Korean Patent Registration No. 10-1778667 (registered on Sep. 8, 2017) discloses a battery module including unit modules in which a cooling fin is disposed between battery cells with being in contact therewith, and cooling plates on which the unit modules are mounted, however, it did not solve the above-described problems.
